This is for one of my users on our Windows 2008 network. We have to domains x.local and Y.corp on our LAN. Users are created on Y.corp and there's two way interdomain trust. users have access to a shared folder SF1 on the X.local domain controller. Whenever the user restarts his computer, he gets an access denied message when he tries to access SF1. If I disconnect shared folder SF1 from his computer and remap it, he gets access rightaway.
This problem only affects one user. All other users are fine.
